De Gea's future at the Theatre of Dreams is in major doubt as he has refused to sign a new contract with the Red Devils.

As a result of his failure to pen a new deal, the 24-year-old - who joined United in 2011 - has been linked with a move to Real Madrid.

Madrid boss Carlo Ancelotti is understood to be a big admirer of the Spaniard and is allegedly keen on luring him to the Bernabeu to replace Real's veteran keeper Iker Casillas.

According to several reports in Spain, Ancelotti is fed up with Casillas' below-par performances and is desperate to offload him this summer to make room for De Gea - who used to play for Real's local rivals Atletico Madrid.

However, the former Chelsea chief has rubbished the speculation linking him with a move for the Spanish international and has insisted last season's Champions League winners don't need to sign another goalkeeper.

"I see myself here next season with Casillas." Ancelotti said.
